latch f are other elements of the lock vwhich This invention relates to a remote control for latches, and is especially adapted for automobile door latches, wherein it is desired to control the latch from a remote point which enables the occupant to open the autofirst, a

mobile door without leaningforward in the seat, as is the case with the latch controls now most generally used. Y l

The ob'ect of the invention is toiprovidef etachable connection between the latch unit and the actuator which permits the easyv assembly of the parts and which enables l the Amanufacturer to ship the latch, draft member and actuator separately. The delltachable connection may be very easily installed with a minimum amount of labor.

The second object is to provide a lost motion connection between the latch and the actuator. With such a lost motion connection it is possible to actuate the latch independently of the remote control and the draft connections which connect the actuator with the latch proper.

Thirdly, it is the object to provide a remotely located independent actuator which is controlled by'a rotary spindle that can protrude thru the garnish moulding of the car.

Another feature is the provision of means to prevent rattling between the rotary spindle and the slide carried by the actuator plate, and to hold the slide of the remote actuator from moving back and forth.

In the drawings:

Fig. 1 is a side elevation of a latch and a remote control therefor.

Fi 2, 3, 4 and 5 are sections taken on the hne 2 2, 3 3, 1 -4, and 5-5 of Fig. 1 respectively.

Fi 6 is a'. detail vin perspective of the draft mem r.

Fig. 7 is a detail in perspective of the slide.

Fig. 8 is a detail in perspective of one end of the sliding bolt.

Fig. 9 is a section on the line 9--9 of Fig. 1.

The lock comprises a casing a, which slidably sup orts the sliding bolt b. A coil sprlngc ars against the struck-out ear d, carried by the bolt for projecting the same from out of the casing in the position shown in Fig. 1. The roll-back e andthe nightare of standard construction and formno part of this invention. The inner end of the sliding bolt is provided with the struckup lug g, the upper portion of said struck-up lug being twisted about the axis of the lu and inclined at an angle to the longitudina axis of the sliding bolt to provide a head, as clearl shown in Fig. 8.

A dra t member h is provided at one end with a slot 'i which is arranged to enga e over this struck-up lug carried by the sli ing latch bolt. To assemble the draft member to the latch, it draft member so that the slot i will pass over the twisted head'of the lug. e The draft member can then `be partially rotated and isnecessary to`tilt the 1 engaged over the lower portion of the lug when returned to the straight line position, or in other words, to the position which is parallel to thelongitudinal axis of the bolt. The twisted portion of the lug serves as a head to revent the accidental displacement of the raft member or disconnection between the draft member and bolt.

At a remote point from the latch an actuator plate k is located and the vertical rotary spindle mis journaled in said plate, the lower portion of said rotar spindle being bowed out to form the cran portion n.. A coil spring o is engaged about the spindle and exerts a pressure on the spindle to urge the same in a clockwise direction, as viewed from below in Fig. 1. -The actuator plate is rooved as at p, and in this groove is slidab supported the actuator slide r. This slide as shown in Fig. 7, is provided with the abutment s, a struck-out ear t and the fairly wide slot u. The'draft member h is provided with the foot lv which is under-cut as at w, and the same may be connected to the slide by tilting the slide and inserting the foot v and thedraft member sideways into the slot u, which engages the foot under the slide. The actuator may now be'partially rotated to bring the same into a straight line osition with the draft member and the sliding bolt. The foot of said draft member will now be'caught under the slide and the cutaway portion of said draft member per- 10 mits the draft member to be projected up through the slot u, and the movement of the slide will impart a corresponding movement to the draft member.

Y As the rotary spindle is rotated in a counter clockwise direction, as viewed from below -in Fig. 1, the crank portion of the spindle will engage the abutment 8 carried by the slide and move the slide to the left, which will move the latch bolt or retract the same through the draft member 7i. The spring c in the 'latch casing will again project the bolt when the handle a: secured to the vertical spindle is released. This spring will cause the abutment s to bear against the crank portion of the spindle and the coil spring o secured to the spindle exerts a pressure thereon to bind the crank portion of the spindle against the struck-up ear t. It will thus be seen that the vertical spindle vis held tightly between the abutment s and the ear t, which therefore prevents any rattling of the actuator, and prevents the -'slide moving back and forth.

The draft member iz may be connected to the actuator or sliding bolt by the detachable connection as described. This permits the actuator and latch unit to be connected together when assembled in the automobile bod and enables the manufacturer of the latc to shipthe actuator, lock and draft member separately, the same being assembled by the body manufacturer when the latch and actuator are installed in the body.

- ted to slide freely in the The slot i at the end of the draft member providesfa lost motion connection between the sliding bolt and draft member. This allows the sliding bolt to be actuated or retracted independently of the actuator unit and draft member and when the said latch is actuated independently the draft member remains stationary, the luog bein permitslot i. T e spring o which exerts a pressure on the slide rovides sucient friction between the s ide and the groove p to revent the draft member and slide from in moved when the latch isy actuated indepen ently of the remote l control. But thisvforce is slight, and is easily overcome when the vertical spindle is actuated to operate the latch.

Preferably, we set the actuator unit and the latch unit in the latch board and dok not cut out the intermediate portion of the latch board between the two units. This will cause the draft memberh to be bowed out, as shown in F' 9, thereby preventing the draft member om rattling at the point where it is connected to the slide and to the bolt. Also this rovides a slight amount of friction whic resists the rectilinear movement of the draft member. v

As described, the draft-link h has a slot z' connection with thelatph, and has a somew at similar connection with the'control member, namely, the foot v with the unbodies, the combinationl of easily hooked up by simply putting them together and effecting a relative sliding movement between them. lVe have therefore identified this quickly detachable connection in some of the claims by this relative sliding movement and in others of the claims by ieferring to it as a hooking action.
